,WAD-WlNDiNG MACHINE SPECIFICATION forming part of Letters Patent No. 365,054, dated June 21, 1887.

Application filed Jannanvfltl, 1856. Serial No. lPftlfil. (Nomodcld To (ZZZ 1071 0721 it may concern.-

Be it known that I, AMos DICKERMAN, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in \Vad- Winding Machines; and 1 do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in machines for automatically winding and in troducing wadsinto tubes for paper cartridgeshells; and it consists in certain details of construction and combinations of parts as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in side elevation of a machine embodying my invention, with the shield or guard removed. Fig. 2 is a plan view thereof, with a portion of the bed broken away. Fig. 3 is a view of the machine, partly in end elevation and partly in section. Fig. 4 is a detail view showing the ends of the spindle, the sleeve, the reciprocating heads, and the cutter. Fig. 5 is a detail view of the feed'rolls; and Fig.6 is a detached perspective view of the stripeutter.

The strip A, from which the wads. are formed, is coiled and placed upon a spindle, B, in a case, C, in which the coil is retained by a removable plate, D, fitting over the end of the spindle and held in place by a thumbnut, E, located upon the end of the same, the said case having a standard, F, secured to the bed G of-the machine. From the case the strip is led through a horizontal guide, H, to a pair of feed-rolls, I and J, forming the stockfeed, and each provided with a canrface, K, and respectively secured to shafts L and M, mounted in bearings N N. The shaft L is provided with a pinion, O, meshing with a pinion, P, secured to theshaft M, which is provided at its opposite end with a bevelpinion, Q, meshing with a similar pinion, R, carried bynn upright shaft, S, mounted in the bed of the machine in' bearings T and provided at its lower end with abevel-pinion, U, meshing with a similar pinion, V, carried by a horizontal shaft, W, suspended beneath the machine in bearings X, and provided at its opposite end with a bevel-pinion, Y, meshing with a similar pinion, Z, located upon the driving-shaft A, which is suspended beneath the bed of the machine in bearings B and driven through a pulley, (1, or otherwise. The said feed rolls 1 and J' feed the strip A over a table, I), and into a horizontal sleeve, E, through an opening, F, formed in theside thereof. As the strip enters the sleeve it is guided by the converging beveled faces G l of the movable heads H, and 1 between the ends J J of the bifurcated spindle K, which rotates and winds the wad, the same filling the sleeve E, which corresponds in internal diameter to the diameter of the wad. The said movable heads It and l are located opposite each other and between the bifurcated spindle and the opening F in the sleeve E, and reciprocate in vertical planes through openings L L, formed in the latter. As the wad develops, the heads being held in contact with it by springs M. M, they are gradually retired into chambers N N, formed in the upright 0' against the tension of such springs, which are located in the said chambers and encircle the stems P P, with which the heads are provided, and which have bearing in and extend above and below the upright 0, respectivcly.

The spindle K extends through a hollow shaft, Q, having its opposite ends mounted in the upright O and in the upright It, and provided with an elongated slot, S, receiving a key, T, secured to the spindle, whereby the latter is coupled with the shaft with a capacity for reciprocation therein. At its forward end, andjust to the rear of its ends J J, the spin dle is provided with a wad remover or follower, U, playing in the sleeve E, and located in the rear end thereof when the wad is winding, and serving to remove the wad from. the spindle and to introduceit into the tube when finished. The plunger is not moved forward until the wad has been wound and the 1novable heads H and I retired; but, to guard against possible collision, the rear faces of the ends of the heads are beveled, as at V V, so that in case the heads are not pushed back cutirely out of the way of the follower by the wad the engagement of the follower with the IOU ' to the under face of the bed ofthe machine beveled faces V V of the heads will complete their retirement without injury to the machine.

The hollow shaft Q carries a fixed disk,\V, provided with a fr ictionsurfaee,-X, and also a loose pulley, 1",: provided with a frictionsurface, Z, driven by a belt, A, from any convenient source of power and shifted on the shaft for periodically applying and relieving the friction between the two surfaces by a forked lever,f B. The said lever B is fulcrumed on a stud, G", standing above the bed of the machine, and has its oppositc'end connected through a spring, D", made adjustable in tension by a thumb-screw, E, withan upright arm, F extending upward throngh and playing in a slot, G", formed in the bed of the machine, and'carried by a lever, H", pivoted and provided at its opposite end with an antifriction roll, I", engaging with a cam, J",

niou'nted upon the driving-shaft A aforesaid.

' The tension of the spring D determines the amount of friction developed between the friction-surfaces X and Z when'in contact, and this should always be less than the friction developed between the wad and sleeve when a the former is completed and wound to full size,

so that such friction, being greater than that between the said surfaces, willsu-flice to arrest the rotation of the hollow shaft and the spin dle when the wad is'wound to full size before the friction between the friction surfaces is relieved. In this connection it may be explained greater than that'bet'ween the frictionsurfaces' stops the spindle, while the surface Z slips 7 upon the surface X until the period of. ap-

plied friction expires, or, in other words, until the anti-friction roll P passes the drop of the cam J. l

-The severing of the completed wad from the strip A is effected and controlled by the wad,

which, by retiring the'movable head 1', operates a strip-cutter or knife, K, connected therewith in cutting the strip justias the wad is finished.

The tubes L, into which the wads are introduced, are carried in the pockets M of a tubecarrier wheel, N, rotating in a vertical plane in front of the machine and mounted on a shaft, 0, suspended beneath the bed thereof and rotated to bring the tubes into alignment with the sleeve E, and consequently into position. to receive the wad by. a pawl, O, engaging with .a rack, I, carried by the said wheel and controll d y a spring, 1?", and carried by a lever, Q hung in a bearing, It, depending from the bed of the machine, and having its rear end slotted, as at S, to receive a pin, T mounted in a wheel, U, secured to the driving-shaft A.- A"shield or guard, V",- fitting over' the tube-carrier wheel, as shown in Fig.

1 of the drawings, and secured to the bed of the machine, prevents the tubes from being displaced when the wads are introduced into them. A wad, Y, introduced into'one of the tubes L, is shown in Fig. 1 of thedrawings.

The reciprocation of the spindle K for operating the follower U to cjectthe wad is an .tomatically controlled by thewad which retires the movable head I and engages the stem P thereof with a screw, X", located in the end of a lever, Y, fulcrumed in an arm, Z, depending from the frame of the machine. The opposite end of such lever supports and actuates a pivotal arm, A", pivoted to an operating-lever, B fulcrumed beneath the bed of the machine and carrying an anti-friction roll, 0 engaging with a cam, D .located uponthe shaft A, andhaving attached to it a spring,

E3, for keeping the said roll in contact with The pivotal arm A is pro-- the said cain. vided with a beveled nose, F, adapted to enter anoteh, ,G, formed in the .lower end of a pivotal arm, H", the forked upper end of which is connected with the rear end of the spindle K through'a-grooved disk, l,'secured thereto; A heavy spring, J", encircling the rear end of the spindle, is providedfor retracting it after it has been thrown forward by the arm H, which is actuated for the purpose from the is coupled with the arm H by the pivotal arm Afl'which is lifted for such purpose by the le'ver'Y", controlled by the wad through the movable head I. The said spring J" is inter: posed betwcenthe grooved disk Paforesaidand'a clutch, K, carrying a pin, L", ,extending through a slot, M formed in the spindle K, whereby the clutch is coupled with the spindle with acapacity for reciprocation there upon. Lugs N, located upon the upright Ij; engage with the clutch K for stopping the spindle in position to receive the endof the strip A between its ends 'J" J. A light spring, 0 interposed between the said clutch-and upright, serves to disengage the former fromthe lugs N aforesaid afterthe retraction of the spindle and the insertion of the strip between the ends thereof. i

The operation of the machine is as follows: The feed-rolls I and J are timed so that immediatcly after the-retraction of the spindle K succeeding the introduction of the previously wound wad into the tube, they will engage their cam-faces K K with the strip A and advance it forward,'so as to effect the insertion of its end between the ends J J of the spindle- K, after which the eam faces are carried beyond the range of the strip, which is leftfree' to be drawn. in by the spindle. Then the pulley Y is moved upon the hollow shaft Q through its connections with the driving-shaft driving-shaft A through the lever B", which applied friction, according to the time occu-' pied in winding the wad, thetime so consumed .being dependent uponthe thickness of the the-stem P and in actuating the latter in moving the V spindle forward, so as to eject the completed gaged with the lugs N (see Fig.'2,) located spindle, being now disengaged from the by the frictiondeveloped between the wad and anti-friction roll (3 of the lever B passes over A andits friction-surface X engaged with the friction-surface Z of the fixed disk Vi, which is secured to the said'shaftQ, and the pulley Y being rapidly rotated through the belt A the shaft Q and the spindle K are actuated in rapid rotation. As the spindle rotates it winds the wad from the strip A, which is free to be drawn in by the spindleas described. As the wad develops, it gradually retires the movable heads H and I, which are in-contact with it from the beginning, and finally pushes them entirely out of the sleeve E. The spindle .will now be stopped either sleeve, or by the termination of the period of paper.

The retirement of the head 1 during the development ofthe wad has'l ipfirated throughof the said head to cause the lever Y. to lift .-the-pivotal arm A into-position for the entrance of its nose F into the notch G of thearm H this relation of parts obtaining or being brought aboutwhen the zwad has been, wound to full size and the spindle stopped, after which the lever B is, actuated-through its connection with the: ."drivi ng-shaft A" ,in coupling the pivotal arm A with the arm H wadand to introduce it into the tube, which has been brought into position for the purpose by the tube-carrier wheel N, the ejection of the wad being effected by the follower U, can riedby the spindle. As the'spindle is moved forward, as described, the spring 0 being lightergthan the spring J is first compressed and the clutch brought into position to be enupon the upright R. Further forward movement of the spindl-e'compresses the spring J which operates after the introduction of the wad into the tube to retract the spindle. Before this retraction occurs, however, the

wad, is free, and will be sufiicientlyrotated by the loose pulley Y, there lleing enough friction between the same and the shaft Q to rotate the latter, and hence the spindle K, to engage the clutch K with the lugs N whereby the spindle is brought into position for the insertion of the strip between its. ends J J. After the heavysprin-g 'J has expanded, and in so doing retracted the spindle, the lighter spring 0 expands and the clutch K is disengaged from the lngsN, leaving the spindle K free to be rotated. Meantime, and before the said lugs and clutch have been disengaged, and while the spindle isheld against rotation, the cam-faces K K of the feed-rolls I and J have been brought into engagement 7 claim as new,

It is to be noted also that in my improved, machine the cutting of the strip after the wadhas been wound is automatically controlled by the wad, which does not, therefore, depend for unil'o the length of the strip orils thickness.
